// Conversion factor: 1 knot = 1.15078 MPH
// Bidirectional Conversion Logic:
MPH = knots × 1.15078
knots = MPH ÷ 1.15078
// Example 1: Type "10" in knots
MPH = 10 × 1.15078 = 11.5078
// Example 2: Type "50" in MPH
knots = 50 ÷ 1.15078 = 43.4488
// Bidirectional Conversion Logic:
MPH = knots × 1.15078
knots = MPH ÷ 1.15078
// Example 1: Type "10" in knots
MPH = 10 × 1.15078 = 11.5078
// Example 2: Type "50" in MPH
knots = 50 ÷ 1.15078 = 43.4488
